May I recommend a book to you all by an animal behaviourist called "Animals Make us Human". Excellent book. I think it is on the NYT best seller list now. It is not an animal rights book--rather, it is a book on how to treat animals, even in captivity, to impart a minimum amount of stress. The book provides insight on how these animals live, what gives them pleasure, what stresses them, and overall, what makes them tick.
In my opinion, after reading this book, we should not be exploiting any wild animals for our entertainment. That means dolphins, whales, lions, elephants, etc. Even if it means a shorter lifespan, the quality of life is something you have to consider. (For orcas, captive whales do not live as long, so even more reason to free them).
FYI, dogs are not wild animals...they have evolved to become domesticated, and in fact, they probably would not survive without humans (wolves would, of course). But we Yorkie owners already know that
